SPECIFICATION forming part of Letters Patent No. 493,042, dated March 7,1893.

Application filed June 20,1892. $erial lid 87,343. (No model.)

To all whom it may concern:

Be it known that we, ALBERT A. PAGE and WILLIAM E. SPARKS, of New Haven,in the county of New Haven and State of Connecticut, have invented a newImprovement in Bells; and I do hereby declare the following, when takenin connection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure 1, a view of the bell from the rear showing the operating lever.Fig. 2, a top or front View with the belland upper plate 0, removedshowing the operative mechanism. Fig. 3, a vertical central sectionshowing parts in side View. Fig. 4, a transverse section cutting on linew:c of Fig. 3 looking down upon the lever.

This invention relates to an improvement in that class of bells adaptedfor door and similar purposes, and in which a clock work with a mainspring is employed as a means for operating the hammer, the mechanismbeing normally locked so as to prevent its operation upon the hammer,but released by a push or pull applied to the locking device, so thatupon such push or pull the mechanism will operate to strike the belluntil such push or pull ceases, then the stopping of the operation ofthe mechanism will be automatic, the object of the invention being asimple looking device, certain in its action, and not liable todisarrangement, and the invention consists in the construction ashereinafter described and particularly recited in the claim.

A, represents the base by which the bell is held or secured in anydesired position. Within the base is one plate B, of the clock-work.

C, represents the second plate of the clockwork, which is supported uponthe plate B, by the usual pillars. On the plate C, the center-post D, isarranged or formed, and upon the outer end of the post the bell E, issecured, in the usual manner, the bell being preferably of a sizecorresponding to the base, so that the bell with the base forms aninclosure for the clock-work. The operating mechanism is arrangedbetween the plates B and C, in the usual manner, and consists of acenterwill cause the rotation of the arbor in the opposite direction. Onthe arbor the main gearwheel H, is arranged, in the usual manner,

with a spring-pawl connection I, which engages a ratchet-wheel J, onthecenter-arbor F, all in the usual manner. The main-wheel H, worksdirectly or indirectly into an arbor K,which carries an escapement-wheelL. The hammer M, is attached to an arbor N, and the shaft N, carries averge 0, adapted to work into the escapement-wheel L, and so that underthe revolution of the escapement-wheel L, a vibratory movement will beimparted to the hammer, in the usual manner, and so that when free, thereaction of the spring will cause the escapement wheel to revolve, andthe hammer to vibrate, the hammer being adapted to strike the bell, allin the usual manner.

As a means for locking and releasing the mechanism, a lever P, is hungupon a fulcrum Q, upon the rear or under side of the plate B, and so asto swing in a plane parallel with the axis of the arbors of theclockwork, and a suitable spring R, is arranged, the tendency of whichis to force the lever P, outward, or away from the plate B, andyieldingly hold it in such position. Thepallet-arbor N, extends throughthe plate B, and near its outer end is constructed or provided with acollar S, which is flattened upon its two sides, as seen in Fig. l. Thelever P, extends toward the projecting end of the arbor N, and is con- 95 structed with a slot T, which in Width corre sponds to the narrowerwidth or diameter of the collar S, and so that under the action of thespring R, the lever P, will normally stand engaged with the collar S, asseen in Figs. 1, I00 3 and 4, and because of the fitting of the narrowor angular collar S, into the corresponding slot T, of the lever P, thehammer-arbor is held against rotation, and thereby the mechanism lockedto prevent its operation, but when the lever P, is turned upon itsfulcrum, as indicated in broken lines Fig. 3, so as to throw the leverout of engagement with the l ion of the hammer through an esc'apment- 1wheel and a pallet on the hammer-shaft, nor

arbor N, then themechanism is released, and free for operation under thereaction of the spring. The operation of the lever may be made by meansof a pull from a distant point, through a wire U, attached to a tail Vofthe lever P, the pull upon which will impart the disengaging movementto the lever, and so soon as the pull is released, the reaction of thelever spring will throw the lever again into engagement with the collarS, and lock the mechanism, and so hold it stationary or in sus'penseuntil again released.

The releasing device may be by means of a push spindleW, applied tothelever, as seenin Fig; 8, and so that a pull will force the lever to itsdisengaging position. The spring is wound by means of a handle X,applied to the outer end of the center-arbor,

bntthe winding mechanism may be any of the 5 u hold it; in* suchconnection,- the lever being j adapted to be turned upon its fulcrum outof known devices whereby the required rotary movement may be given tothe spring-arbor to prod-ucethe winding.- Thelever while outside theplate B,is brought within the base A,

so that when the base is secured, the' lever will i V specification inthe presence of two subscribing witnesses.-

be free for operation, as clearly seen in Fig.3. While it is preferredto attach the collar to or form it upon the hammer arbor, it will beevident that it may be applied to any other arbox of the mechanismbetween the centerand hammer arbors, and it will be also evident thatthe shape of the collar is immaterial except that it be angular, and soas to be embraced by a corresponding slot or recess in the lever.

From the foregoing it will be understood that we do not claim broadly abell provided with a clock mechanism to produce the operado we claimbroadly the combination of such mechanism with a locking device wherebythe the said mechanism may be held in suspense and released by a push orpull applied to the locking mechanism, but

What we do claim as our invention is The combination of a base carryinga bell, a clock-work composed of a main-spring and mechanism forimpartin g vibration to the hammer-arb'or, an arbor of the saidmechanism constructed with an angular shaped collar, a lever arranged toswing in a plane parallel 1 with the axis of said arbor, and constructedwith a slot corresponding to'said angular col- 1ar,a spring the tendencyof which is to throw the said slotted lever into engagement with thesaid collar of the shaft and y'ieldingl'y engagement with said arbor,substantially as l and for the purpose described.

In testimony whereof we have signed this ALBERT A,- A -a WILLIAM E.SPARKS.
